SPECIFICATION forming part of Letters Patent No. 614,726, dated November22, 1898.

Application filed April 30, 1898- Serial No. 679,287. (No model.)

To ctZZ whom it may concern.-

Be it known that we, TEODOR KIERAKO WICZ and J OSEF LUCAS, citizens ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in Hubsfor Vehicle-Wheels; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention relates to a novel construction in a hub for vehicle andparticularly bicycle wheels, the object being to provide a device ofthis character which will serve as a cushioned support for the frame;and it consists in the features of construction and combinations ofparts hereinafter fully described and claimed.

In the accompanying drawings, illustrating our invention, Figure 1 is afragmentary side elevation of the rear end portion of a bicycleframe inwhich a hub constructed in accordance with our invention is mounted.Fig. 2 is a sectional View on the line 2 2 of Fig. 1. Fig. 3 is asectional View on the line 3 3 of Fig. 2. Fig. 4 is a detail endelevation of the inner drum. Fig. 5 is a top plan view of'the bridge.

The hub A of the vehicle-wheel is mounted upon an inner drum B, aboutwhich it revolves, ball-bearings 0 being interposed between said drum Band hubA and adjusted by means of the cone 1. The ends 2 of the drum Bare closed by means of the plates 3, each of which is provided with aslot 4, extending radially across the center thereof, but not to theperiphery. Said plates 3 are so placed that the slots 4; correspond inposition, so as to permit the passage therethrough and guide a bridge 5,formed of a single piece of metal adapted to support the frame 0 of theGuide-bolts 7 and 8 pass through said drum 13 parallel with each otherand with said slots 4 in said plates 3 and pass through openings in saidbridge 5, which is slidingly movable on and also guided thereby. Saidbolts 7 are provided with large screw-threaded heads 9, adapted to fitwithin the screwthreaded openings 10 in said drum B and at their otherends are adapted to receive collars 11, adapted to fit snugly withinopenings 12 in said drum B. Springs 13 are adapted to be interposedbetween said bridge 5 and the heads 9 of said bolts and springs 14.between said bridge 5 and said collars 11. Said collars 11 beingadjustable are adapted to regulate the tension of said springs 14. Thebolts 8 are mounted in said drum 13 between the bolts 7 in any suitablemanner and are adapted to serve as guides to hold the supplementalsprings 15 in position to receive the bridge as the latter approachesthe lower limit of its movement, thereby preventing it from striking thelower end of the slotin case of an unusual jar.

The end portions 16 of the bridge 5 are screw-threaded and are adaptedto normally project from the center of the drum B, while the portionthereof within the drum extends upwardly in the manner of a crank, thusenabling longer and thus more yielding springs to be interposed beneathsaid bridge than would otherwise be possible. Plates 17 are looselymounted upon said end portions 16 of said bridge 5 adjacent the plates 3and are adapted to protect the slots 4: against the admission of dust.Annular flanges 18 are mounted upon the flanges of said hub A andproject inwardly slightly over the drum B, thereby preventing theentrance of dust into the bearings O.

The hub herein shown illustrates the hub of the rear wheel of a bicycleand is therefore provided with the usual means for securing asprocket-pinion thereon and securing the device in the frame, and suchmeans being common we omit description of same. The springs 13 serve toprevent the bridge from striking the upper ends of the slots i whenreboundmg. I

We claim as our invention 1. A hub for vehicle-wheels comprising the hubproper revolubly mounted upon a drum rigidly held against rotation,slots in the ends of said drum, a bridge passing through said drum andsaid slots, guide bolts rigidly mounted in said drum and passing throughsaid bridge,- springs surrounding said guidebolts and bearing againstsaid bridge, and means for mounting the projecting portions of saidbridge in the vehicle-frame,- substantially as described. 7

2. A hub for vehicle-wheels comprising the hub proper revolubly mountedupon a drum rigidly held against rotation, slots in the ends of saiddrum, a bridge passing through said drum and said slots, guide boltsrigidly mounted in said drum and passing through said bridge, springsaround said guide-bolts hearing at one end against said bridge and attheir other ends against adjustable collars on said bolts, and means formounting the projecting portions of said bridge in the vehicle-frame,substantially as described.

A hub for vehicle-Wheels oomprisin g the hub proper rotatably mountedupon a drum rigidly held against rotation, a bridge passing centrallythrough said drum and having a crank-shaped portion Within said drum,guide-bolts passing through said drum and through said crank-shapedportion of said bridge, and springs interposed between said crank-shapedportion of said bridge and the end portions of said guide-bolts,substantially as described.

4. A hub for Vehicle-wheels comprising the hub proper rotatably mountedupon a drum rigidly held against rotation, a bridge passing centrallythrough said drum and having a crank-shaped portion Within said drum,guide-bolts passing through said drum and through said crank-shapedportion of said bridge, springs interposed between said crank- 0 TEODORKIERAKO\VIOZ.
